Brief Summary:
This trial aims to study the efficacy and safety of cannabidivarin (CBDV) in children with ASD.

Condition or disease Intervention/treatment Phase
Autism Spectrum Disorder Drug: Cannabidivarin Drug: Matched Placebo Phase 2

Detailed Description:

There is a clear unmet need for new therapeutics to treat irritability in children with ASD that do not have the metabolic and weight adverse event profiles of the currently approved treatments. Cannabidivarin (CBDV) is a nonpsychoactive phytocannabinoid and a safe variant of Cannabidiol (CBD). It has no appreciable tetrahydrocannabinol (THC) [less than 0.01%], has been shown to have no impact on weight or metabolism, and improves both social and cognitive functioning in animal models of idiopathic and syndromal autism (Fragile X, Rett Syndrome, Angelman Syndrome). The CDC currently estimates 1 in 59 children have ASD. ASD is characterized by deficits in social communication, irritability, repetitive behaviors, impulsivity, temper tantrums, and high caregiver burden. Currently, the only FDA-approved medications for symptoms of ASD are aripiprazole and risperidone, both of which are indicated for irritability in pediatric ASD. These medications are effective but are associated with considerable side effects with long term treatment in this chronic developmental disorder, including weight gain, metabolic syndrome and the risk of type 2 diabetes, prolactin elevation and growth of breast tissue, extrapyramidal symptoms and the risk of tardive dyskinesia. The anticonvulsant divalproex sodium (valproate/VPA) also significantly reduces irritability and repetitive behaviors in individuals with ASD. Although VPA is efficacious for pediatric epilepsy and some symptoms of ASD, it also has significant side effects, including weight gain, sedation and nausea. CBDV, like VPA, is effective in the treatment of pediatric epilepsy, and ASD mouse models demonstrate potential mechanisms for treatment with CBDV, including potential therapeutic effects on repetitive behaviors, irritability, sociability, and quality of life, and the capacity to reduce inflammation. This study aims to examine the efficacy and safety of cannabidivarin (CBDV) with a primary aim of studying its effect on irritability in children with ASD.

STUDY DESIGN: This is a 12-week randomized, double-blind study of CBDV vs. placebo in 100 child and adolescent subjects aged 5 to 18 years with a diagnosis of ASD.

Criteria

Inclusion Criteria:

  1. Male or Female pediatric outpatients aged 5 to 18 years old
  2. Diagnosis of Autism Spectrum Disorder (ASD) confirmed by the ADOS-2 and DSM-5 criteria
  3. Aberrant Behavior Checklist (ABC) - Irritability Subscale score of 18 or greater at screening visit
  4. Social Responsiveness Scale (SRS) score of 66T or higher at screening visit
  5. Clinical Global Impression Scale - Severity (CGI-S) score of 4 or higher at screening
  6. Stable pharmacologic, educational, behavioral and/or dietary interventions for 4 weeks prior to randomization and for the duration of the study.
  7. Physical exam and laboratory results that are within normal range for individuals with ASD
  8. Presence of a parent/caregiver/guardian that is able to consent for their participation and complete assessments regarding the child's development and behavior throughout the study

Exclusion Criteria:

  1. Exposure to any investigational agent in the 30 days prior to randomization.
  2. Prior chronic treatment with CBD, CBDV or an endocannabinoid treatment.
  3. Positive testing for THC or other drugs of abuse at the screening or baseline visits upon repeat confirmation testing.
